Do the daytime running lights work at night on a 1999 Chevy Tahoe?

No, the daytime running lights (DRLs) on a 1999 Chevy Tahoe, and most vehicles with DRLs, are designed to only function during the daytime. At night, your headlights should be on, and the DRLs will typically turn off. The system is designed to increase visibility during the day without the extra drain on the battery that the headlights would cause.
